摘    要：体系转换法加固多孔拱桥，就是在原结构上增设部分卸载杆系，将强度不足部位的内力转移至强度有余的部位，藉以提高原有结构的承载能力．通过理论分析和实验研究，证明体系转换法加固多孔拱桥可靠易行，效果显著.

Abstract: To strengthen multiarch bridges with system transfer method is in essence to add an unloading member system to the original structure so as to move the internal force from the parts with insufficient strength to the parts which have a surplus of strength, thus increasing the supporting ability of the original structure. Through theoretical analysis and experimental research, system transfer method has been proved reliable and practicable in strengthening multiarch bridges.
